Paying tribute to the Ireland supporters at Murrayfield, RBS 6 Nations winner Luke Fitzgerald said: "Thanks a million to the fans from the all guys. They were fantastic. We really felt their support out there, they were the '16th man' and helped us get over the line."

Sean O'Brien scored two tries and produced a man-of-the-match performance as Ireland beat Scotland 40-10 to finish top of the table and retain the RBS 6 Nations title. He spoke to Irish Rugby TV afterwards.

Speaking to Irish Rugby TV after the trophy presentation, RBS 6 Nations winner Robbie Henshaw said: "Words can't describe it...just the whole atmosphere, everyone in the stadium, just the way it ended out. It was pretty intense, the heart was rushing."

Enjoying the post-match celebrations at Murrayfield, RBS 6 Nations winner Rory Best said: "It's been a bit of an emotional roller-coaster, the last hour. The crowd have been absolutely incredible. We're just delighted to give something back to them."

Previewing this week's trip to Murrayfield, Ireland's Robbie Henshaw said: "Scotland have a really nice back-line, we're going to have to be sharp on our feet and defend really well. We'll have to match them physically and bring some line speed."

Primed to come on off the bench against Wales, Ian Madigan said: "Especially when you're in that second sub spot in the back-line, having played in different positions for Leinster this season it definitely helps me. It's been nice the way the (recent) games have unfolded (for me). I feel very much part of the team."

Looking forward to playing again at the Millennium Stadium, Ireland hooker Sean Cronin said: "It's one of the best places to play in world rugby. It's got an amazing atmosphere and the crowd are so passionate there."
